Containers and methods of using the same

ABSTRACT

Disclosed herein are containers. Also disclosed are methods using the containers and methods of storing substances in containers. The containers have a glass base and a plastic cap and provide for child-resistant containers. A user can releasably remove the cap from base. For example, the user squeezes opposite corners of the container cap, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base.

The present application claims priority from U.S. provisional application No. 63/112,135 filed Nov. 10, 2020 and U.S. provisional application No. 63/195,662 filed Jun. 1, 2021, both of which applications are incorporated by reference herein in their entirety.

TECHNICAL FIELD

The present disclosure relates to glass containers that can be used for storage and provide child-resistant safety features.

BACKGROUND

Containers intended for storing substances or materials are often designed to prevent opening by a child and yet can be manipulated by adults, including seniors, to gain access to the substance. These “child-resistant” containers are typically used for over the counter and prescription medications. Other child-resistant containers are used for other household items, that are toxic if swallowed or ingested, such as laundry detergent and cleaners. These systems are in place to prevent children from inadvertently gaining access to the contents of these containers.

Generally, child resistant containers include a multi-step opening process or require steps to be completed simultaneously. A certain level of mental and physical dexterity is required for opening such a container, making it difficult for children to access the contents within. For example, use of a certain amount of pressure or force while a second action is completed is needed to open such a container prevents children from being able to open and access the contents of the container.

A challenge in creating child resistant containers is making the container easy enough for the elderly and other individuals to be able to use. For example, some child resistant containers offer a screw-cap or pop-top closure, and although they are efficient for child resistance, these devices pose a degree of hardship for individuals with wrist and finger joint inflammation or arthritis.

Currently available child resistant containers are also often inadequate in protecting the contents from degradation upon exposure to environmental factors such as light including ultraviolet (UV) radiation, moisture, temperature, bacteria, physical damage or air.

Also, most screw cap medicine containers lack external features favorable for counting, sorting, and stacking and do not allow for efficient inventory management.

SUMMARY

In view of the above, there remains a need for improved containers that are easy to use for an elderly or disabled individual, while providing child-resistant features. Also, there remains a need for a container where the contents are protected for improved shelf-life, such as being liquid-tight, air-tight, non-stick, or having other desirable properties.

The present disclosure relates to a container. In certain aspects, the container is generally polygonal in shape, for example, generally square, rectangular, diamond, quadrilateral, or rhomboid in shape. In other aspects, the container may have a rounded shape such as substantially circular, oval or oblong.

In certain preferred aspects, parts of the container, such as the container base, are made substantially of glass. Child-resistant glass containers are described in PCT Applications PCT/US2020/017237 and PCT/US2020/017242, the contents of which are hereby incorporated by reference in their entirety.

The disclosed containers have a container base and a container lid (or cap). The containers provide improved packaging and storage of substances or materials in a controlled environment. In certain preferred aspects, the containers provide, for example, an air-tight, liquid-tight, water-tight, humidity-controlled, light-controlled, non-stick, anti-static, or any combination thereof, environment.

In one aspect, the present disclosure is directed to a container that is child-resistant. In some aspects, the container is not child-resistant. In certain aspects, the container includes a substantially symmetrical container base and/or cap. In one aspect, the container is substantially square in shape. Preferably, the substantially square container has rounded corners.

In one preferred aspect, a container is provided that comprises (a) a container base comprising: a closed bottom end; an open top end; a first undercut and a second undercut positioned on the base; and (b) a container cap comprising a first engagement feature and a second engagement feature, wherein the first engagement feature is configured to secures to the first undercut and the second engagement feature is configured to secure to the second undercut.

In certain embodiments, the first undercut and second undercut are on opposed sides of the base, for example the first undercut and second undercut may be on opposed or opposite corners or sides of the base, preferably in substantially matching or parallel positions on opposed container sides.

In certain embodiments of such aspect, preferably the first engagement feature is configured to provide a locking engagement with the first undercut and/or preferably the second engagement feature is configured to provide a locking engagement with the second undercut.

In certain embodiments of such aspect, the container also may comprise an engagement element in addition to the first and second engagement features and first and second undercuts. For instance, suitable additional engagement element comprises a locking bar, one or more teeth elements, or other arrangement.

In a further preferred aspect, a container is provided that suitably comprises: (a) a container base comprising: a closed bottom end; an open top end; one or more locking bar elements on the base; and (b) a container cap comprising one or more engagement features that mate with the one or more locking bar elements. In certain embodiments, a locking bar element extends vertically from the container base. While a container may comprise one or more locking bar elements, such as 1, 2, 3, or 4 or more locking bar elements, in certain embodiments a container may comprise a single pair (two) of locking bar elements. The one or more locking bar elements may be based at varying positions of a container. In a preferred configuration, each one of a pair of locking bar elements is positioned on an opposed sides of a container, for example at substantially mating positions on facing container walls.

In certain embodiments, suitably a container cap comprises an engagement portion configured to mate with a locking bar element. For instance, in one preferred design, a container cap comprises a pair of engagement portions configured to mate with a corresponding pair of locking bar elements of the container base.

In a yet further preferred aspect, a container is preferred that comprises (a) a container base comprising (i) a closed bottom end and (ii) an open top end; and (b) a container cap that releaseably mates with the container base, wherein one of the base or cap comprises a tab portion, and the other of the base or cap comprises an engagement feature configured to mate with the tab portion. In one preferred container system, the tab portion is a releasable latch element. In a further preferred container system, the cap comprises one or more tab portions and the base comprises one or more engagement features configured to mate with the tab portion. In one embodiment, a cap may comprise a pair of tab portions, preferably on opposed sides of a cap, such as where each tab of the pair are at substantially mating or parallel positions on facing container sides.

In certain embodiments of this aspect, a tab portion may be movable (e.g. hinge-type motion and/or pivoting around a fixed tab end) upon releasable mating with an engagement feature. In a particular design, a tab portion may laterally pivot upon mating with an engagement feature.

In another preferred embodiment of this aspect, the container may comprise a tab portion element which comprises one or more tab portions. For instance, the element may be a ring that contains or more tab portions and that is associated with, for example circumscribes, a container cap or base.

In a further preferred embodiment of this aspect, an engagement feature that mates with a tab portion may configured as an aperture such as a slot or other opening of a base or cap, preferably where the aperture is present in a container base with one or more tab portions positioned on the container cap. Suitably, a tab portion engages a sidewall of an engagement feature (e.g. tab portion engages the lower sill of a slot) to provide releasable mating of the base and cap.

In a further preferred aspect, a container is provided that suitably comprises: (a) a container base that comprises (i) a closed bottom end, (ii) an open top end, and (iii) one or more locking elements on the base; and (b) a rounded container cap comprising one or more engagement features that mate with the one or more locking bar elements.

In such aspect, preferably the container cap is upwardly rounded, i.e. substantially dome-shaped with the cap circumference being square, rectangular, oval, circular or other shape of the container.

In preferred systems, actuation such as downward pressure by a user on the cap top surface disengages an engaged cap and base. For example, in a preferred system, actuation such as downward pressure applied by a user on a top center region of the container cap disengages an engaged cap and container.

In certain preferred embodiments of such aspect, a locking element such as a locking bar extends vertically from the container base that may be disengaged by actuation of the cap top surface as discussed. In a particular design, the base suitably comprises a single pair of locking elements, for example a pair of locking bar elements with each element of the pair positioned on opposed sides of the base. Suitably, a cap may comprise an engagement portion configured to mate with a base locking element, for instance, where a cap comprises a pair of engagement portions configured to mate with a corresponding pair of locking bar elements positioned on a container base.

In a yet further aspect, a container is provided that comprises (a) a container base comprising (i) a closed bottom end and (ii) an open top end; and (b) a cap that releasable engages with the container base upon engaging the base and cap, wherein at least one of the base or cap comprises an inner layer that preferably provides enhanced releasable engagement or sealing of the cap and base. The inner layer provides enhanced engaged or sealing relative tov to the same container that does not include the inner layer. Thus, an inner layer can be assessed empirically for enhanced engagement or sealing, for example a container that includes the inner layer can be assessed for reduced water ingress into the closed container with inner layer submerged in water or other fluid relative to a comparable container without the inner layer, or the closed container with inner layer can be assessed for reduced air flow relative to a comparable container without the inner layer. In preferred aspects, the inner layer can facilitate or provide a substantially air-tight seal of the container with the cap and base in engaged, closed arrangement. The term air-tight is used herein in its customary meaning and may include the ability of the container to restrict airflow in and/or out of the container for extended periods, including the ability to maintain a differential pressure (e.g. maintaining a pressure differential that commences as a positive or negative pressure at least 2, 3, 5, 8, or 10 percent above or below ambient atmospheric pressure) for an extended period such as 1, 6, 12, 24, 48, 72 or 96 hours or longer. Unless otherwise indicated, an air-tight container or seal or a water-tight container or seal as referred to herein is a container o seal that does not permit notable water penetration (naked eye inspection) upon submerging the closed container in water for 60 seconds.

The inner layer may be composed of one or more of a variety of materials such as a polymer or rubber material. Preferred inner layer materials may include for example, a fluoropolymer or thermoplastic elastomer.

The inner layer may be positioned in varying configurations, including where the cap comprises an inner layer material and/or where the base comprises an inner layer material. In one system, the cap inner surface comprises the inner layer, for instance, where the cap portion that contacts an engaged base comprises the inner layer. In one preferred system, the cap periphery surface that contacts the base comprises the inner layer. One or more inner layer materials suitably may be incorporated at varying positions, but preferably will be present at abutting surfaces of the cap and base of the container. One or more inner layer materials may be present on one or both of the cap and base. In one preferred system, a cap may comprise an inner layer material and the base surface that abuts the cape inner layer may be configured to facilitate engagement with the inner layer, for example the engaging base surface may comprise a material or surface texturing that facilitates secure and preferably substantially air-tight engagement with the inner layer of the cap. In another preferred system, a base may comprise an inner layer material and the cap surface that abuts the base inner layer may be configured to facilitate engagement with the inner layer, for example the engaging cap surface may comprise a material or surface texturing that facilitates secure and preferably substantially air-tight engagement with the inner layer of the base. In yet another preferred system, the cap and base sources that abut in a closed container configuration both may comprises an inner layer material.

In some embodiments, the container base includes a glass, a polymer glass, a glass-ceramic, a ceramic material, or a combination thereof. For example, the glass is selected from the group consisting of an amber glass, a green glass, an opal glass, and a transparent glass.

In some embodiments, the container cap includes a polymer, a plastic, or a combination thereof. For example, the polymer includes a thermoplastic elastomer (TPE), a thermoplastic vulcanizate (TPV), a thermoplastic polyurethane (TPU), polypropylene, polypropylene copolymer, ultra-clarified polypropylene, colored polypropylene, PET, PETE, polycarbonate, polystyrene, or a combination thereof.

In some embodiments, the container cap further includes an annular sealing ring positioned on an inner surface of the top end of the cap. The annular sealing ring includes a thermoplastic elastomer (TPE), a thermoplastic vulcanizate (TPV), or a thermoplastic polyurethane (TPU).

In some embodiments, the container is substantially air-tight, liquid-tight, light resistant, temperature resistant, moisture resistant, bacteria resistant, tamper resistant, child resistant or a combination thereof.

Other materials or additives can be added to the container base, container cap or both. For example, in one embodiment, the container cap and/or base further comprise a liner. In some embodiments, the liner is thermoformed, die-cut, or injection molded. In another embodiment, the liner includes a polymer, for example a fluoropolymer. In some embodiments, the fluoropolymer is FEP (fluorinated ethylene propylene), PTFE (polytetrafluoroethylene) or PFA (perfluoroalkoxy alkanes).

In another embodiment, the container cap and/or base comprise polytetrafluoroethylene (PTFE) coatings. In one embodiment, clear plastisol is applied to an exterior surface of the glass base to prevent breaking and makes the glass opaque. In another embodiment, oleic acid vapor is added to prevent glass from sticking together on production line. In yet another embodiment, SiO₂ vapor is deposited to a plastic cap to provide a flexible layer of glass.

In some embodiments, the container includes a tamper evident element. For example, the tamper evident element is a seal, a tape, or a combination thereof. In another embodiment, the modular container includes an RFID tag.

In some embodiments, the child-resistant container includes a writing surface compatible with a pen, a pencil, or a marker.

In some embodiments, the container cap includes a polymer. For example, the polymer includes a thermoplastic elastomer (TPE), a thermoplastic vulcanizate (TPV), a thermoplastic polyurethane (TPU), polypropylene, polypropylene copolymer, ultra-clarified polypropylene, colored polypropylene, PET, PETE, polycarbonate, polystyrene, or a combination thereof.

Another aspect of the present disclosure includes a method of affecting a child-resistant closure of a container. The method includes providing a child-resistant container comprising a container base and a container cap and sliding the container cap over the open end of the container base, wherein the first and second cap engagement elements engage with and couple to the one or more base engagement elements.

In some embodiments, the method of affecting a child-resistant closure of a container further includes removing the container cap by simultaneously applying about 1 to about 10 pounds of external compression force to opposite sides of the container cap and pulling the container cap off of the container base. In one embodiment, a user applies about 2 to about 8 pounds of external compression force to opposite sides of the container cap and pulling the container cap off the container base. In another embodiment, a user applies about 3 to about 7 pounds of external compression force to opposite sides of the container cap and pulling the container cap off the container base. In another embodiment, a user applies about 4 to about 6 pounds of external compression force to opposite sides of the container cap and pulling the container cap off the container base.

The present disclosure related to containers. As discussed, the container may include a container cap, wherein the container cap is sized and configured to mate with the container base.

In certain preferred aspects, the containers are square or substantially square (e.g., having rounded corners and/or sides) in shape. Aspects of present disclosure include methods for using the containers (e.g., for creating child-resistance and for storing or holding a material). The containers can be understood more readily by reference to the following detailed description of the disclosure. It will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the invention.

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” includes two or more elements.

Ranges can be expressed herein as from one particular value, and/or to another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent ‘about,’ it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.

As used herein, the terms “about” and “at or about” mean that the amount or value in question can be the value designated some other value approximately or about the same. It is generally understood, as used herein, that it is the nominal value indicated ±10% variation unless otherwise indicated or inferred. The term is intended to convey that similar values promote equivalent results or effects recited in the claims. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but can be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. In general, an amount, size, formulation, parameter or other quantity or characteristic is “about” or “approximate” whether or not expressly stated to be such. It is understood that where “about” is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.

The terms “first,” “second,” “first part,” “second part,” and the like, where used herein, do not denote any order, quantity, or importance, and are used to distinguish one element from another, unless specifically stated otherwise.

As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. For example, the phrase “optionally affixed to the surface” means that it can or cannot be fixed to a surface.

As used herein, the terms “cap engagement element” and “cap engagement mechanism” are used interchangeably. Similarly, the terms “base engagement element” and “base engagement mechanism” are used interchangeably.

As used herein the terms “cap” and “lid” are used interchangeably and refers to the closure element that secures over a container base.

Moreover, it is to be understood that unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not actually recite an order to be followed by its steps or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow; plain meaning derived from grammatical organization or punctuation; and the number or type of aspects described in the specification.

It is understood that the containers, materials and devices disclosed herein have certain functions. Disclosed herein are certain structural requirements for performing the disclosed functions, and it is understood that there are a variety of structures that can perform the same function that are related to the disclosed structures, and that these structures will typically achieve the same result.

The containers described herein are preferably configured to be child-resistant. The disclosed containers provide an improved packaging and storage of substances or materials in a controlled environment, providing, for example, an air-tight, liquid-tight, water-tight, humidity-controlled, light-controlled, or any combination thereof, environment. The containers comprise a container base and a container cap. The container base is made up of any suitable material. For example, the base is made from glass (e.g., any non-crystalline amorphous solid) or other glass-like materials (e.g., porcelain, thermoplastics). The container is generally polygonal in shape. For example, the container base and/or container cap are generally square, rectangular, diamond, quadrilateral, triangular, or rhomboid in shape. In some aspects, the container base and/or the container cap is substantially square, square, and/or square with rounded edges. The sides of the container are planar or substantially planar such that they are slightly concave or convex.

Child-Resistant Containers

As disclosed herein, the containers generally comprise a base and a cap. The combination and attachment of the base with the cap provides a child-resistant container. In some embodiments, the base can be attached or tethered to the cap. In other embodiments, the base and the cap are not tethered.

The cap and the base are sized and shaped to enable attachment with each other. The container is also sized and shaped to provide a container that is substantially air-tight, liquid-tight or both. These properties regulate the amount of air, oxygen, water, water vapor, humidity, and/or liquids that can enter or leave the container when in a closed position. The container can also have light-blocking (e.g., UV) properties. The container can also have other desirable properties, such as non-stick surfaces, anti-static surfaces, tamper resistance, child-resistance, or combinations thereof. The container can also prevent or impede the growth of microorganisms such as bacteria and fungus.

The base of the container has a neck and a foot or support. The foot or support forms a closed bottom end and the neck forms an open top end. The neck has attachment means (e.g., a cap engagement mechanism) for attaching to a cap. The cap also has attachment means (e.g., a base engagement mechanism) for attaching to a base, such as the neck of the base.

The overall shape of the container is generally square or square with rounded corners when viewed from the top (e.g., horizontal cross-section). The container is generally square, square with rounded corners, generally rectangular, or rectangular with rounded corners when viewed from the side (e.g., vertical cross-section). The container cap can form a substantially flush side or edge with the base (e.g., the foot or support of the base) when in a closed configuration. The length to width ratio of the base and/or the cap is about 1:1 (i.e., generally square). The height of the base, relative to the length and/or width, can vary and can be smaller or larger than the length and/or width. A height that is substantially the same to the length and width forms a generally cube-shaped structure. A height that is different (e.g., larger or smaller) than the length and width forms a generally rectangular cuboid or rectangular prism shaped structure. Embodiments of the container base and/or container cap are substantially symmetrical in shape.

In some aspects, the container base is generally a unitary structure. In some aspects, the base neck extends from the support or foot. In some aspects, the diameter of the neck is less than the diameter of the support. When a container cap is placed on a container base, the cap sits flush with the support. This can add to the child-resistance of the container. For example, a flush side can prevent children from getting under the cap by using nails/teeth to open.

As described herein, the base and/or cap can be composed from a variety of materials. The base generally has a rigid structure. This is generally non-deformable under normal conditions (e.g., user hand strength). The cap generally has a non-rigid or semi-rigid structure. The cap is generally deformable and/or elastic under normal conditions. Non-limiting examples of materials to form a rigid or non-deformable structure includes glass and metals. The container base can be made from glass, polymer glass, glass-ceramic, and/or a ceramic material. For example, the glass can be flint glass, amber glass, green glass, opal glass, transparent glass, recycled glass, tempered glass, soda lime glass, borosilicate glass or others. Non-limiting examples of materials to form a deformable and/or elastic structure includes plastics, polymers, and rubbers.

As described herein, the container cap is configured to associate with the container base. The container base forms an enclosure for containing materials, and the container cap encloses the open top end of the base. One aspect of the child-resistant container is the container is configured to store, hold and/or preserve a substance or a material as well as providing a mechanism for child-resistance. In a closed configuration, the container is substantially child-resistant, that is, a child would have a difficult time removing the container cap from the container base.

Container

FIGS. 1-25 illustrate various embodiments of the containers described herein. The container base is generally symmetrical in shape. For example, the container base has a length to width ratio of about 1:1. In some embodiments, the base is generally polygonal in shape. In some embodiments, the container base is generally square, rectangular, diamond, quadrilateral, or rhomboid in shape. In one some embodiment, the container base is substantially square, square, and/or square with rounded edges. The sides, edges and/or corners of the container base can have a slight curvature, such that the base is generally and substantially square in shape with rounded corners or edges. The containers described herein have features to make them child-resistant. Other features will be readily apparent in light of the foregoing.

The container bases described herein can be sized and configured so that the base (e.g., cavity) has a total storage volume of about 1 ml (milliliter) to about 2000 ml, about 2 ml to about 1000 ml, about 3 ml to about 500 ml, about 4 ml to about 100 ml, about 5 ml to about 50 ml, or about 5 ml to about 10 ml. In some embodiments, the volume of the container base is 1 ml, 2 ml, 3 ml, 4 ml, 5 ml, 6 ml, 7 ml, 8 ml, 9 ml, 10 ml, 11 ml, 12 ml, 13 ml, 14 ml, 15 ml, 16 ml, 17 ml, 18 ml, 19 ml, 20 ml, 25 ml, 30 ml, 40 ml, 50 ml, 60 ml, 70 ml, 80 ml, 90 ml, 100 ml, 150 ml, 200 ml, 250 ml, 300 ml, 350 ml, 400 ml, 450 ml, 500 ml, 600 ml, 700 ml, 750 ml, 1000 ml, 1250 ml, 1500 ml, or 2000 ml. In some embodiments, the storage volume of the container base is less than 1 ml or greater than 2000 ml.

Corner Pinch Square Container

Referring to FIGS. 1A-3F, square container 100 has cap 100A and base 100B. Locking features 101A on cap 100A mate with corresponding locking features 101B on base 100B. Locking features 101 are positioned on opposite corners of cap 100A and base 100B. Container 100 has a generally square shape with rounded corners. Since cap locking features 101A mate with base locking features 101B on corners 110A and 110C, a user must pinch opposite corners 110B and 110D on the cap where these locking features are not placed in order to remove cap 100A from base 100B.

Cap 100A has a outer top surface 106, interior surface 107, ceiling 109, locking features 101A, and non-locking corners 110B, 110D. Locking features 101A are positioned on opposite corners of interior surface 107 of cap 100A. Base 100B has locking features 101B, bottom outer surface 102, outer side surface 103, interior side surface 104, floor 108 and corner 105. Locking features 101B are positioned on opposite corners of the neck of base 100B. Locking features 101A and 101B are sized so that 101A fits in or with 101B. Locking features 101A and 101B creates an anti-rotational mechanism so a user cannot twist or turn the cap off. Instead, the user pinches opposite corners (110B, 110D) of cap 100A to release retention features 101 on the cap from the base. The free space on the corners allows for the cap to flex and release itself on the opposite corners.

Flat Base and Cap

Referring to FIGS. 4A-7G, another embodiment of a square container 200 has lid 200A and base 200B. Base 200B has a bottom end 201, locking bar 202, inner corner 203, cavity 204, undercut 205 formed between the neck and foot, and top end 206.

Methods of Using and Storing

The present disclosure relates to a method for packaging and/or storing a material. The method of packaging comprises providing a child-resistant container and introducing the material into the container.

The material being packaged can be a material sensitive to one or more environmental factors. Sensitivities include, but is not limited to, air, water, oxygen, light, UV, temperature, bacteria, other microorganisms, or combinations thereof. For example, the material is a consumer product, pharmaceutical, nutraceutical, herbal material, botanical material, food product, animal-based product, plant-based product, or the like. The containers disclosed herein create a substantially air-tight seal, liquid-tight seal or a both.

The cap engagement mechanism and base engagement elements are configured to cooperatively engage in a locked position that releasably secures the container cap to the container base in a closed position in which the open end of the base is covered by the cap prohibiting access to the open cavity. Securing the container cap on the container base comprises the following steps: sliding and pressing the container cap over the open end of the container base along the long axis of the container. The container is locked by sliding and pressing the cap over the cap engagement mechanisms of the container base, until an audible noise is heard as well as a tactile snap. In other words, the sides of the container cap have to be pressed with a force sufficient to overcome the hindrance of the base engagement elements and then settle in a secure base-cap engagement, such that the base engagement elements of the container cap fit within or around the cap engagement mechanism. This forms a secure coupling of the base engagement element of the container cap and the cap engagement mechanism of the container base. Additional grooves and ridges can be included in order to increase the hardship or complexity of accessing the contents or using the container.

In some embodiments the complete coupling of the base engagement mechanism and the cap engagement element is designed to release an acoustic signal, a snap-sound, which lets the operator know that the cap is secure on the base and thereby the contained elements are secure in the child-resistant container.

Visual signals are provided on the surface of the container which correspond to the site and direction of force to be applied. For example, one or more markings are provided on the surface of the container base, designating the side of the container base that does not have the cap engagement mechanisms. The markings correspond to application of pulling force on the container cap to dissociate the cap from the base, while the container base is held by another hand.

To access the contents from a closed container, application of a predetermined amount of compression force inward on two opposing sides of the cap is necessary. For example, the method of affecting a child-resistant closure of a container further comprises removing the container cap by simultaneously applying compression force on opposite sides of the container cap. One would press two opposing sides of the cap not having the cap engagement mechanism, and resiliently reduce a first width of the cap along a compression axis to a second width, which releases the cap engagement mechanism from the base engagement element. This frees the cap from the pressure of the ramps and/or ridges on the sides of the base. In one embodiment, the predetermined amount of force can be applied to a position on opposed caps sides adjacent to the cap engagement elements. The markings on the container base constitute the visual indicator of the side for the application of the compression force in order to open the container. The container cap and container base can be uncoupled from the closed position by axially pulling the container cap away from the container base along a longitudinal axis of the container. The pulling can occur after the engagement elements are in an unlocked position.

The predetermined amount of force is between about 1 to about 10 pounds of external compression force to the container cap and pulling the container cap off of the container base. In one embodiment, a user applies about 2 to about 8 pounds of external compression force to the container cap and pulling the container cap off the container base. In another embodiment, a user applies about 3 to about 7 pounds of external compression force to the container cap and pulling the container cap off the container base. In another embodiment, a user applies about 4 to about 6 pounds of external compression force to the container cap and pulling the container cap off the container base. In some embodiments, the predetermined amount of force is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more pounds of external compression force. In some embodiments, the predetermined amount of force is at least about 3 pounds, at least about 4 pounds, at least about 5 pounds, at least about 6 pounds, or at least about 7 pounds.

The cap engagement mechanism and base engagement element can be configured to disengage from a locked position to an unlocked position in which the container cap and container base can be uncoupled from a closed position to an open position such that the open cavity of the container is accessible. A change from a locked position to an unlocked position is achieved by radially inwardly applying a predetermined amount of compression force at two opposing sides of the cap to resiliently reduce a first width of the cap along a compression axis to a second width, where the second width is slightly less than the first width. In some embodiments, the predetermined amount of force can be applied to a position on opposing base sides, wherein, at least one side of the base comprises the cap engagement mechanism. The cap and base can be uncoupled from the closed position by pulling apart the cap along a longitudinal axis of the container by simultaneously applying a predetermined force of compression on two opposing sides of the cap, where at least one of the two opposing sides comprises the cap engagement mechanism, and pulling the cap away from the base along the longitudinal axis. In still other embodiments, the cap can be pulled using cap sides corresponding to a position parallel to the expansion axis. In some embodiments, the reduction is from a first width to a second width, where the second width is less than the first width, and the second width expands to the first with resiliently upon release of pressure.
